Question

The table shows the results for spinning the spinner 80 times. What is the relative frequency for the event spin a 3?Outcome - 1, 2, 3, 4Frequency - 20, 10, 22, 28Number of trials - 80

Answer 1

Solution

- The formula for finding the relative frequency for an event is:

$\text{ Relative Frequency}=\frac{\text{ Event Frequency}}{\text{ Total Frequency}}$

- The Event of spinning a "3" occurred 22 times. This means that

$\text{ Event Frequency }=22$

- The total frequency is gotten by adding up all the frequencies. That is,

$20+10+22+28=80$

- Thus, we can find the Relative Frequency of getting a 3 as follows:

$\text{ Relative Frequency}=\frac{22}{80}$

Final Answer

The Relative Frequency of getting a 3 is:

$\text{ Relative Frequency}=\frac{22}{80}$
